Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a nasal feeding anti - detachment structure and nasal feeding device. Background Art

[0002] Nasal feeding, that is, the nasal feeding method, means that under special circumstances, a gastric tube is manually inserted into the esophagus through the nasal cavity. First, the food is pureed with a grinder, and a large syringe is connected to the large food injection port below the gastric tube connector. After being firmly connected, the piston of the manual pressure - applying push rod is used to inject water and food into the patient's stomach, helping patients who cannot swallow independently to obtain water and food, and maintaining the body's metabolism, weight, and nutrition.

[0003] For example, a nasal feeding tube fixing device disclosed in the authorized publication number CN106726613B, whose structure includes a hose fixing ring, a fixing buckle, and a connecting buckle. The connecting buckle is arranged on the hose fixing ring, and the fixing buckle is fixedly arranged at the end of the hose fixing ring; however, this application still has deficiencies: after the nasal feeding tube is fixed, the length of its internal part remains unchanged. However, when the patient moves their head, the length of the esophagus will change slightly, which may cause friction between the nasal feeding tube and the esophageal wall. This continuous friction will cause significant irritation to the esophageal mucosa and may cause esophageal pain or even secondary injury in the long run.

[0004] Since the length of the indwelling nasal feeding tube outside the body is relatively long, it is very easy to touch or even pull the nasal feeding tube in daily life, bringing inconvenience to the patient's daily life.

[0005] Therefore, based on the above problems, we have invented a nasal feeding anti - detachment structure and nasal feeding device. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a nasal feeding anti - detachment structure and nasal feeding device to solve the problems raised in the above - mentioned background art.

A gear is provided in the arc-shaped cylinder. A rack is meshed and connected to both the upper and lower sides of the gear. The two racks are respectively fixedly connected to the two fixing brackets. A rotating rod is rotatably penetrated through the arc-shaped cylinder. One end of the rotating rod is coaxially fixed to the gear, and the other end of the rotating rod is fixedly connected to a rotating handle.

[0010] Further, the limiting member includes a limiting groove provided on the inner wall of the storage groove. A wedge-shaped block is slidably connected in the limiting groove. The wedge-shaped block is fixedly connected to the bottom of the limiting groove through a plurality of limiting springs.

[0011] Further, smooth inclined surfaces are provided at both the upper and lower ends of the wedge-shaped block, and the inclined surfaces face away from the bottom of the limiting groove.

[0012] Further, the pressure regulating mechanism includes a fixed cover fixedly installed at the upper end of the fixing bracket. A pressing plate is slidably connected in the fixed cover. The upper end of the pressing plate is rotatably connected to a screw rod. The upper end of the screw rod is threadedly penetrated through the fixed cover and fixedly connected to a rotating handle.

[0013] Further, the fixing bracket is integrally arranged in a U shape, and both arms of the fixing bracket are arched upward to form ear hooks.

[0014] Further, the fixing mechanism includes a fixing plate fixedly connected to the upper end of the sleeve. A sliding rod is slidably penetrated through the fixing plate. A clamping plate is fixedly connected to one end of the sliding rod located on the central axis of the sleeve. A fixing spring is sleeved outside the sliding rod, and both ends of the fixing spring are fixedly connected to the clamping plate and the fixing plate respectively.

[0015] A method for nasal feeding is as follows: S1. Preparation of nasogastric feeding environment: Select a clean, quiet, and comfortable environment, ensure that there are no sundries and dust in the operation area, and wash hands carefully with warm water and soap to prevent infection; S2. Preparation of nasogastric feeding supplies: According to the doctor's advice, prepare an appropriate amount of qualified nutrient solution, select a syringe of the appropriate specification, and ensure that it is clean and intact. Prepare a small amount of warm boiled water, gauze, and a notebook; S3. Inspection of the nasogastric tube: Check the integrity of the nasogastric tube for any abnormalities and confirm the position of the nasogastric tube; S4. Perform nasogastric feeding: Draw an appropriate amount of well-shaken nutrient solution with a syringe. After firmly connecting the syringe to the nasogastric tube, slowly inject the nutrient solution into the nasogastric tube. At the same time, pay attention to whether the patient feels uncomfortable during nasogastric feeding. If the patient feels uncomfortable, immediately stop nasogastric feeding and seek medical help. If the patient does not feel uncomfortable, continue nasogastric feeding; S5. Flush and store the nasogastric tube: After the nutrient solution injection is completed, flush the nasogastric tube with a small amount of warm boiled water to keep the nasogastric tube clean and unobstructed. After flushing and drying, place the nasogastric tube on a fixed bracket, fix it, and wear it behind the ear; S6. Record and tidy up: Record information such as the date, time, dosage and type of nutrient solution, and the nasogastric feeding reaction of the patient in a notebook. Properly handle used supplies such as syringes and gauze to keep the nasogastric feeding area clean.

[0016] Compared with the prior art, the present invention provides a nasogastric feeding anti-disconnection structure and nasogastric feeding, having the following beneficial effects: 1. By setting a fixed bracket, the nasogastric tube located outside the body can be stored and sealed, keeping the nasogastric tube clean, avoiding the situation of touching the nasogastric tube during daily life, and having no impact on daily life.

[0017] 2. By setting a fine-tuning mechanism, when the patient makes a head movement, the esophagus changes slightly. The fine-tuning mechanism drives the nasogastric tube to extend to a certain extent. Under the action of the friction force between the esophagus and the nasogastric tube, the extended part of the nasogastric tube is driven to extend into the body, reducing the friction distance between the nasogastric tube and the esophagus, reducing the stimulation of the nasogastric tube to the esophagus, and avoiding damage to the esophagus.

[0018] This application can slightly extend the length of the nasogastric tube in the body, avoid damage to the esophagus caused by friction with the esophagus, and can store the nasogastric tube located outside the body without affecting the patient's daily life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a nasal feeding anti-disconnection structure and nasal feeding.

[0023] Such as Figures 1 - 10As shown in the figure, a nasal feeding anti - detachment structure includes two symmetrically arranged fixing brackets 1.

Further, the adjusting mechanism 2 includes an arc - shaped cylinder 32 sleeved outside the two fixing brackets 1. Both fixing brackets 1 are slidably connected to the arc - shaped cylinder 32. A gear 34 is arranged inside the arc - shaped cylinder 32. Both the upper and lower sides of the gear 34 are meshed with racks 33. The two racks 33 are respectively fixedly connected to the two fixing brackets 1. A rotating rod 35 is rotatably penetrated through the arc - shaped cylinder 32. It should be noted that the rotating rod 35 is rotatably connected to the arc - shaped cylinder 32 through a damping rotating shaft. One end of the rotating rod 35 is coaxially fixed to the gear 34, and the other end of the rotating rod 35 is fixedly connected to a rotating handle 36. A fine - tuning mechanism 3 is arranged below the fixing bracket 1 for fine - tuning the nasal feeding tube. The fixing bracket 1 and the fine - tuning mechanism 3 are connected by two fixing rods 31.

[0024] In the present invention, a receiving groove 5 matching the nasal feeding tube is arranged at the upper end of the fixing bracket 1.

It should be noted that the limiting member 6 includes a limiting groove 7 arranged on the inner wall of the receiving groove 5. A wedge - shaped block 9 is slidably connected in the limiting groove 7. It should be noted that both the upper and lower ends of the wedge - shaped block 9 are provided with smooth inclined surfaces, and the inclined surfaces face away from the bottom of the limiting groove 7. The wedge - shaped block 9 is fixedly connected to the bottom of the limiting groove 7 through a plurality of limiting springs 8. A pressure - regulating mechanism 4 for regulating the pressure of the nasal feeding tube is arranged on the fixing bracket 1. It is worth mentioning that the pressure - regulating mechanism 4 includes a fixed cover 22 fixedly installed at the upper end of the fixing bracket 1. A pressing plate 23 is slidably connected inside the fixed cover 22. The upper end of the pressing plate 23 is rotatably connected to a screw rod 24. The upper end of the screw rod 24 is threadedly penetrated through the fixed cover 22 and fixedly connected to a rotating handle 25; Through the above - mentioned technical features: Rotate the rotating handle 36. The rotating handle 36 drives the gear 34 to rotate through the rotating rod 35. The gear 34 drives the two racks 33 to move relatively. The two racks 33 drive the two fixing brackets 1 to move relatively until the appropriate position. After nasal feeding is completed, pass the nasal feeding tube through the fixed cover 22 and the arc - shaped cylinder 32 in sequence and press it in the receiving groove 5. The nasal feeding tube is limited by the wedge - shaped block 9. Then rotate the rotating handle 25. The rotating handle 25 drives the pressing plate 23 to move through the screw rod 24. The pressing plate 23 squeezes the nasal feeding tube, and the nasal feeding tube can be sealed to prevent external dust from entering the inside of the nasal feeding tube and keep the nasal feeding tube clean; At this time, wear the fixing bracket 1 on the auricle, and the nasal feeding tube outside the body can be stored to avoid being touched daily and will not affect the daily life of the patient.

[0025] In order to reduce the friction between the nasogastric tube and the esophagus, a fine-tuning mechanism 3 is provided. The fine-tuning mechanism 3 includes a sleeve housing 10 and a fine-tuning frame 11. The fine-tuning frame 11 is installed on the side wall of the sleeve housing 10. The sleeve housing 10 is provided with a through sleeve 12. There are two fixing mechanisms 26 for fixing the nasogastric tube on the sleeve 12. It is worth mentioning that the fixing mechanism 26 includes a fixing plate 27 fixedly connected to the upper end of the sleeve 12. A sliding rod 29 is slidably penetrated through the fixing plate 27. A clamping plate 28 is fixedly connected to one end of the sliding rod 29 located on the central axis of the sleeve 12. A fixing spring 30 is sleeved outside the sliding rod 29. The two ends of the fixing spring 30 are fixedly connected to the clamping plate 28 and the fixing plate 27 respectively. Sliders 13 are installed on both sides of the sleeve 12. It should be noted that a certain extension amount is set for the nasogastric tube located between the sleeve 12 and the fixing bracket 1. Both sliders 13 are slidably connected to the inner wall of the sleeve housing 10. A connecting rod 17 is installed on the front side of the slider 13. There is a through hole 21 on the sleeve housing 10. The connecting rod 17 passes through the through hole 21 and extends into the fine-tuning frame 11. There are two rotating grooves 14 at the inner bottom of the fine-tuning frame 11. A rotating plate 15 is rotatably installed in the rotating groove 14. The lower end of the rotating plate 15 is connected to the inner bottom of the rotating groove 14 through an elastic piece 16. A ball 20 is placed in the fine-tuning frame 11. The ball 20 matches the two rotating plates 15. The two connecting rods 17 are respectively installed on the two rotating plates 15. It is worth mentioning that a sliding groove 18 is provided on the side wall of the rotating plate 15. A connecting block 19 is slidably connected in the sliding groove 18. The connecting block 19 is rotatably connected to the connecting rod 17.

[0026] Through the above technical features: Insert the nasogastric tube into the sleeve 12 and fix it through the fixing mechanism 26. During daily wearing, when the patient makes a head movement, at this time, the ball 20 rolls under the action of gravity and centrifugal force. The ball 20 will press against the rotating plate 15. The rotating plate 15 rotates and drives the slider 13 to descend through the through hole 21. The slider 13 drives the nasogastric tube to move through the sleeve 12, so as to slightly extend the nasogastric tube. When there are some changes in the esophagus, under the action of its friction force, the extended part of the length of this part of the nasogastric tube is brought into the body, reducing the friction distance between the nasogastric tube and the esophagus, reducing the stimulation of the nasogastric tube to the esophagus, and avoiding damage to the esophagus.

[0027] A nasogastric feeding method, the specific steps are as follows: S1. Nasogastric feeding environment preparation: Select a clean, quiet and comfortable environment, ensure that there are no sundries and dust in the operation area, and wash hands carefully with warm water and soap to prevent infection; S2. Nasogastric feeding supplies preparation: According to the doctor's advice, prepare an appropriate amount of qualified nutrient solution, select a suitable specification syringe, and ensure that it is clean and intact. Prepare a small amount of warm boiled water, gauze and notebook; S3. Check the nasogastric tube: Check the integrity of the nasogastric tube, whether there is any abnormality, and confirm the position of the nasogastric tube; S4. Perform nasogastric feeding: Draw an appropriate amount of well-shaken nutrient solution with a syringe. After firmly connecting the syringe to the nasogastric tube, slowly inject the nutrient solution into the nasogastric tube. At the same time, pay attention to whether the patient feels uncomfortable during nasogastric feeding. If the patient feels uncomfortable, immediately stop nasogastric feeding and seek medical help. If the patient does not feel uncomfortable, continue with nasogastric feeding; S5. Flush and store the nasogastric tube: After the injection of the nutrient solution is completed, flush the nasogastric tube with a small amount of warm boiled water to keep the nasogastric tube clean and unobstructed. After flushing and drying, place the nasogastric tube on the fixed bracket 1 and fix it, then wear it behind the ear; S6. Record and organize: Record information such as the date, time, dosage and type of the nutrient solution, and the nasogastric feeding reaction of the patient in a notebook. Properly dispose of used supplies such as syringes and gauze to keep the nasogastric feeding area clean.

[0028] Working principle: For the storage and fixation of the nasogastric tube: Rotate the rotating handle 36. The rotating handle 36 drives the gear 34 to rotate through the rotating rod 35. The gear 34 drives the two racks 33 to move relatively. The two racks 33 drive the two fixed brackets 1 to move relatively until in a suitable position. Insert the nasogastric tube into the sleeve 12 and fix it through the fixing mechanism 26. Pass the nasogastric tube through the fixing cover 22 and the arc-shaped cylinder 32 in sequence and press it in the storage groove 5. Limit the nasogastric tube with the wedge block 9. Then rotate the turning handle 25. The turning handle 25 drives the pressing plate 23 to move through the screw rod 24. The pressing plate 23 squeezes the nasogastric tube to seal the nasogastric tube. At this time, wear the fixed bracket 1 on the auricle.

[0029] Daily wearing of the nasogastric tube: When the patient makes a head movement, at this time, the ball 20 rolls under the action of gravity and centrifugal force. The ball 20 presses against the rotating plate 15. The rotating plate 15 rotates and drives the slider 13 to descend through the through hole 21. The slider 13 drives the nasogastric tube to move through the sleeve 12, and the nasogastric tube can be slightly extended. When there are some changes in the esophagus, under the action of its frictional force, the extended part of the length of this part of the nasogastric tube is brought into the body, reducing the frictional distance between the nasogastric tube and the esophagus and reducing the irritation of the nasogastric tube to the esophagus.
